BREAD-RAISER.

SPECIFICATION forming part of Letters Patent No. 668,753, dated February26, 1901.

Application filed January 20, 1897. Serial No. 619,935. (No model.)

T0 (LZZ whom it may concern: 7

Be it known that I, EDWARD B. KNIPPLE, residing at Broadway, in thecounty of Rockingham and State of Virginia, have invented a new anduseful Bread-Raiser, of which the following is a specification.

My invention relates generally to improvements in bread-raiscrs; and oneobject of the same is to provide an improved construction for thepurpose of effecting the raising of bread, consisting of an inner casingor doughreceptacle and an outer casing, the said casings constitutingbetween them ahot-air cham ber which entirely surrounds thedough-receptacle and which is adapted to receive a' heat-generatingmeans for accomplishing the passing thereinto from without and alsopreventing any gases which may accumulate in the hot-air chamber passinginto the doughreceptacle.

Another object is to provide a means for deflecting the heat and causingthe same to circulate around the dough-receptacle to effect the end inview.

The invention relates to other details of construction, which will befully described hereinafter and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of myinvention with the cover in a raised position. Fig. 2 is a centralvertical section of the same with the cover or lid in a closed orlowered position. Figs; 3 and 4 are perspective views, respectively, ofthe dough-receptacle and the heat-deflector removed from the outercasing.

Referring to the drawings, A indicates the outer casing, supported bylegs a and contracted or made smaller at its lower or bottom portion toform the heating-chamber B. This heating-chamber B has the door 0 forthe purpose of permitting ready access thereto for lighting orextinguishing the lamp D, by which heat is generated, or for cleaning .Fbetween its walls and the Walls of the easing A, said space constitutinga hot-air chamber entirely surrounding the dough-recepta- "ele andcommunicating with the heatingchamber B. Suspended by chain efrom thebottom of receptacle E and above lamp D is a deflector G, of cone shape,for the purpose of deflecting the heat, as indicated by arrows, Fig. 2,and thus preventing the bottom of the dough-receptacle just above thelamp becoming heated to such a degree as to burn or cook the doughcontained therein and insuring a circulation of the heat about the saidreceptacle.

It will be noticed by reference to Fig. 2 that the walls of thereceptacle E extend above the walls of the casing A far enough to permitof the fingers being inserted in the finger-holes at the top of thereceptacle for putting it in or taking it out of the casing. The amountof this'extension above the top of the casing is a distance equal to thedepth of the depending flange f of the cover or lid H, hinged to thecasing A, so that when the' cover is in a closed position, as shown insaid figure, the surrounding flange f rests upon the walls of easing A,while the lid proper seats upon the walls of the dough-receptacle E,thus'closing the said receptacle and the hot-air chamber from dust orother foreign substances in the room and also closing thedough-receptacle from communication with the hot-air chamber,whereby anygases which may accumulate in said chamber are prevented from reachingthe dough. In the top of said lid is placed a glass or other transparentplate I, so that the contents of the dough-receptacle may be viewed fromtime to time as desired, and the lamp-chamber is also provided with asimilar plate J for the purpose of inspecting the operation of the lamp.A thermometer K is placed on the under side of the lid beneath the glassplate,

generated.

By locating the thermometer directly under the glass plate it is locatedWithin the doughraising receptacle and the temperature therein isindicated and not the temperature at the outer wall, Which may bedifferent from what it is 011 the interior of the receptacle from theeffects of drafts of air or other causes.

Outlets 0 and 0 in the front and back, respectively, of the casing A areprovided for the escape of gases from the hot-air chamber.

The dough-receptacle is readily removable for placing the dough thereinor removing the same therefrom, as Will be readily understood.

From the above description it will be seen that I have produced a verysimple, convenient, and effective bread-raiser in which the heat isdeflected an d caused to circulate about a dough-receptacle,Which isclosed from gases from the hot-air chamber and from dust and otherforeign substances from without, and which is very cheap inconstruction.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

In a dough-raising apparatus, the combination with a casing, the bottomof which is provided with a heating-chamber, and the upper portion isperforated, of a removable receptacle within the casing atasubstantiallyuniform distance from the same, the top edges of which extend above thetop of the casing, a cover hinged to the casing whose edges are providedwith a flange of a Width equal to the distance that the receptacleextends above the top of the casing, whereby the cover engages with thetop of the receptacle and closes the same and the casing, a deflectorbelow the bottom of the receptacle, and a heater below the deflector,substantially as described.
